Abstract:In order to solve the problem of fouling,slagging and high temperature corrosion in the high temperature area of a coal-fired boiler of a super supercritical and high parameter unit in a power plant in Anhui,a high-temperature nano ceramic coating is rebuilt on the high temperature heating surface,the fouling and slagging and high temperature corrosion areas.After the transformation,the spray area of slagging and high temperature corrosion conditions are significantly reduced,significantly enhancing the operational safety of the boiler.The boiler thermal efficiency is increased by 0.4%,the transformation of investment 1.98 million,saving fuel costs of 4.13 million,recovering the cost in less than half a fear,with the result of excellent technology and economy.
